Radiomaster MT12 12mm Hex steering wheel adapter for 1/10th scale wheels

So far i'm really pleased with my Radiomaster MT12. However, i generally don’t appreciate the small steering wheels that are standard on most pistol style transmitters.

So i designed a 12mm hex adapter shaped like a slotted and drilled brake rotor to fit regular 1/10th scale wheels. And since everybody knows that painted brake calipers produce at least 50 more horsepower, i also added a beefy 6-piston version. Unfortunately the trim switch labels are no longer visible.

The parts can easily be 3D printed using FDM or SLA. No supports needed. Only two 1.5mm screws (about 6-10mm long) and maybe some double sided sticky tape are needed for assembly.
